Miniature circuit breaker, flame-retardant housing PA66 4P automatic for commercial buildings AC 400 V 25 A

Features:

1. [Flame-Resistant Housing] Our circuit breaker is made of PA66 nylon, which offers excellent flame-retardant safety performance.
2. [Short-Circuit Protection] When the circuit is short-circuited, the electromagnetic tripping mechanism can stably cut off the current, making it safer to use.
3. [Rapid Arc Extinction] The circuit breaker can quickly extinguish the arc to prevent electrical fires and ensure your safety.
4. [Easy Installation] The circuit breaker has a double-clip locking structure, which can be operated horizontally during installation, and can be freely disassembled and assembled in confined spaces.
5. [Wide Application] Miniature circuit breakers are widely used in power distribution protection in civil, commercial, and industrial buildings.
